process of using openGL--is setting up buffers and binding before draw

initialization (once) :

create VAO / vertex array
create VBO / vertex buffer
create EBO / element buffer <-- only if using indices

(
glDrawTriangles( // no indices

glDrawElements( // with indices
)

glGenVertexArrays(1,&.. 
glBindVertexArray(..

glGenBuffers(1,&..
glBindBuffer(GL_ARRAY_BUFFER,..
glBufferData(GL_ARRAY_BUFFER,..GL_STATIC/DYNAMIC_DRAW)

// prepare 3x floats for position values for shader
glVertexAttribPointer(0,3,GL_FLOAT,GL_FALSE,0,(void*)0)
glEnableVertexAttribArray(0)

// element buffer add if using indices--
glGenBuffers(1,..
glBindBuffer(GL_ELEMENT_ARRAY_BUFFER,..
glBufferData(GL_ELEMENT_ARRAY_BUFFER,..GL_STATIC/DYNAMIC_DRAW)

initiation done//
